Ở một loài thực vật, tính trạng hình dạng quả do 2 cặp gene (A, a và B, b) phân li độc lập cùng quy định, kiểu gene có allele A và B cho quả dẹt, các kiểu gene còn lại cho quả dài; tính trạng màu sắc hoa do 1 gene có 2 allele quy định, allele D quy định hoa đỏ trội hoàn toàn so với allele d quy định hoa trắng. Cho cây quả dẹt, hoa đỏ lai với cây quả dẹt, hoa trắng thu được F1 đồng loạt quả dẹt, hoa đỏ. Cho các cây F1 giao phấn ngẫu nhiên thu được F2 có tỉ lệ kiểu hình là: 165 cây quả dẹt, hoa đỏ : 60 cây quả dẹt, hoa trắng : 27 cây quả dài, hoa đỏ : 4 cây quả dài, hoa trắng. Biết không có hiện tượng đột biến và các cây quả dẹt, hoa đỏ ở F2 có 8 loại kiểu gene.      Hãy cho biết các cây quả dài, hoa đỏ ở thế hệ F2 có bao nhiêu loại kiểu gene?
